> So a manned mission is currently infeasible. But maybe in the future.

Given the increased interest in manned missions and recent technology advancements/investments, I wouldn't be surprised if we could get there in 15-20 years, which sounds likely to be when it'd need to be refueled.

If it's worth it or too dangerous to send an astronaut to deal with the dangerous refueling operation are whole other questions. But actually getting there? I think we can do it in 15-20 years.

Maybe but it might be obsolete by then, especially considering how much lift capacity Starship will bring online. Will be a lot cheaper to just replace Webb.

It sounds like the main cost (time & $$$) with the Webb was R&D, not the actual launch. Am I wrong?

The main cost was testing. Another big cost was tooling, much of which has been lost.
